RANGE.

SPECIFICATION forming part of Letters Patent No. 548,004, dated October15, 1895..

Application filed November 9, 1894. Serial No. J N Infi l- To all whomit may concern.-

Be it known that I, JOHN MATTSON, a citizen of the United States, and aresident ofv Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Ranges, of whichthe following is a specification.

fire, but which are fitted with means of supplying a current of hotwater which may be used for heating buildings or other purposes; and itcomprises a system of communicating Water tubes or pipes located withinthe range or heater, certain of said tubes or pipes being stationary andothers being movable; and the invention further consists in theconstruction and novel arrangement of parts as hereinafter specified,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan view, with certainparts in section, of a range or heater embodying my invention. Fig. 2 isa vertical section on the line 2 2 of Fig. 1. Fig. 3 is an endelevation, and Fig. 4 shows a range connected with a radiator.

Referring by letter to the drawings, A designates the walls of a range,stove, or heater having the oven'a, the fire-chamber a, and a chamber athrough which the products of combustion discharge.

A shows stationary circulating-pipes arranged sinuously Within the rangeor heater adjacent the side walls. These pipes A extend from the rearportion of the heater through the combustion-chamber and into thefire-chamber. An inlet or feed pipe B communicates through branches 1)with the side pipes A. One or both of the branches 1) may have aconnecting-joint b, so that said pipes may be easily inserted oradjusted. A nest or series of sinuous tubes B is arranged within thecombustiomchamber a These tubes B afiord a larger extent of circulationfor the water than is given by the side pipes A. I have here shown themas communicating with the top and bottom portions of the side pipes. Byreferring to Fig. 2 it will be seen that the tubes alternate in thisarrangement. The

tubes B and the pipes A are, of course, stationary and afford a largearea of heating-surface for water. To provide a still greater ex= tentof circulating-area and heating-surface, I employ a sinuous pipe 0,which may be extended into the fire-chamber of the heater. This pipe Ois arranged horizontally and communicates at its ends with the sidepipes A.

For the purpose of regulating the heat of the circulating water to agreater or less de- This invention relates to ranges or furnaces. forcooking and other direct heating by the gree and also of enabling thefire to be used to a greater or less extent for the direct heating ofvessels set over it, the circulating-pipe O is made adjustable ormovable into and out of the fire-chamber. With this end in view and tomaintain com munication with the pipes A the end portions 0 of theadjustable circulating-pipe O have telescopic connection with the upperend portions 0 of the pipes A. The portions 0' of the pipes A arepreferably made of a length substantially equal to the width of thefire-chamber, and the portions 0 of the pipe 0 may be of substantiallythe same length as the portions 0. Stufting-boxes O are connected to theends of the portions 0. As a means for moving the adjustablecirculatingpipe 0, I prefer to employ gear-wheels O mounted on a shaft 0having bearings in arms 0 extended from the said pipe O. The gears cengage with racks 0 arranged adjacent to the inner side walls of theheater within the combustion-chambers. One end of the shaft 0 ispreferably projected outward through two horizontal slots or openings 0in the side Wall of the heater, and this end is adapted to be engaged bya crank or other suitable instrument. Obviously by rotating the shaft bymeans of a crank or otherwise the adjustable circulating-pipe 0 may bemoved to any desired position. A pipe O leads from the adjustablecirculating-pipe 0 (here shown as from its central portion) and hastelescopic communication with a discharge-pipe G which is extendedthrough the rear wall of the range or heater, and a circulating-pipe 0leads from the pipe O to connect with a radiator or number of radiatorsO A-regulating-valve 0 may be attached to the discharge-pipe.

D designates a vertically-adjustable rear Wall for the fire-chamber. Thewall'D may bemade of fire-brick or other suitable material to resistheat. It may be moved or adj usted to any desired position to regulatethe amount of heat discharged into the combustion-chamber, and, in fact,it may be moved to a position with its upper edge above the plane of theadjustable circulating-pipe C when said pipe 0 shall have been whollymoved into the combustion-chamber, which may be desirable at timesforinstance, in hot weather, when water for heating purposes is not wanted.As a means for moving the back wall D, I provide it with racks d, whichengage with gear-wheels d, mounted on a shaft having suitablejournal-bearings in the heater and having one end extended through awall of the heater, so that it may be engaged by a suitable instrumentto rotate the gears.

It will be seen that by my construction all the pipes form in effect acontinuous sinuous circulating-pipe,one portion of which is a fixture,while another portion of it is adjustable, so that a greater or lessextent of the whole may be utilized for heating water, as circumstancesrender expedient.

Having described my invention, what I claim is- 1. The water heatingsystem consisting of sinuous side pipes, a horizontally adjustable pipehaving telescopic connection with the side pipes, and mechanism foradjusting the latter, substantially as specified.

2. The water heating system consisting of stationary side pipes, ahorizontally adjustable pipe having telescopic connection with the sidepipes, and a discharge pipe having telescopic connection with the saidadjustable pipe, substantially as specified.

3. The range or heater having the fire chamber and the chamber throughwhich the products of combustion discharge, the side pipes extended intoeach of said chambers, the series of pipes located in the last namedchamber and having communication with the side pipes, and the adjustablepipe movable into each of said chambers, substantially as specified.

4. The combination with water circulating and heating pipes in ranges,ofthe vertically adjustable wall D, having racks cl thereon, the gearwheels at engaging with the racks and mounted on a shaft having suitablejournal hearings in theheater A; for regulating the exposure of saidpipes to the fire substantially as specified.

. Signed at New York city, in the county of New York and State of NewYork, this 1st day of November, A. D. 1894.
